DEVELOPING DEVICE AND ELECTROPHOTOGRAPHIC DEVICE

摘要

A developing device which develops a latent image on a photosensitive drum using toner comprising a development roller, reset roller, and a toner agitating paddle, all of which are disposed so that a paddle gear disposed on the rotating shaft of the toner agitating paddle is meshed with both a first gear disposed on the rotating shaft of the development roller and a second gear disposed on the rotating shaft of the reset roller. Also a doctor blade is disposed so that a toner thin-layered area to supply toner onto the surface of the development roller is formed in a triangle obtained by connecting the rotating shafts of the development roller, reset roller, and toner agitating paddle.
